Small rolled pieces of toilet paper stained with feces that are created when vigorously wiping the bum crack after a shit.
Tiny worm shaped pieces of the paper fall off the wad and lay around the toilet seat or the floor area around the pan that look like shitty little maggots
'For fucks sake Dave, you've left bog maggots on the seat again. Can't you wipe your arse like any normal person?'
'..Sorry love'
